Think about it.  Your spouse comes up to you and says, “The doctor said I only have a year to live.”  Then would it matter so much that he forgot to take out the trash—again?  Would you care if she left the garage door open more times than she closed it?  And would it still annoy you that he got lost but refused to stop and ask for directions?  None of us knows exactly how much more time we’ll have with our spouse.  So this Valentine’s Day, try to overlook the little, annoying things. Love your spouse like you don’t know if they’ll be here tomorrow—because in reality—you don’t.   Here’s how one man wrote himself letters from the future to be sure he lived each day to the fullest.
